Abstract

A method for computing includes specifying a data processing system using a logical system definition, which defines logical system components having respective functionalities and a topology for interconnecting the logical system components. The logical system components are represented using respective logical objects in a hierarchical object model. Physical resources of a grid computer system are represented using physical objects in the hierarchical object model. The logical objects are automatically mapped to at least some of the physical objects, so as to allocate the physical resources to carry out the respective functionalities of the logical system components. The allocated physical resources are configured and activated so as to cause the grid computer system to function as the data processing system, in accordance with the logical system definition.
